[Feature] Update native OneSignal SDKs dependencies to 5.1.x

[shepherd-l]

Description

One Line Summary

Updated included OneSignal Android SDK to 5.1.1 and OneSignal iOS SDK to 5.1.0

Details

Motivation

Applies native fixes from the OneSignal Android SDK and OneSignal iOS SDK to the Unity SDK

• OneSignal Android SDK 5.1.1 Release Notes
  • Includes location behaviour change from 5.1.0:
    • You will need to include location permission in your own app's manifest
• OneSignal iOS SDK 5.1.0 Release Notes

Scope

Unity developers must target API level 33 or higher to build for Android. This is because androidx.work:work-runtime-ktx:2.8.1 from the OneSignal Android SDK requires compileSdkVersion 33 or higher.
Older versions of Unity do not include Android 33 by default - 2022 and below, so users will have to download it. Steps on how to do so are listed in the Unity docs: Setting the Android SDK Target API.

Testing

Manual testing

Tested OneSignal initialization, app build with Unity 2022.3.10f1 of the OneSignal example app on a emulated Pixel 4 with Android 12 and physical iPhone 12 with iOS 15.5.

Checklist

Overview

• I have filled out all REQUIRED sections above
• PR does one thing
  • If it is hard to explain how any codes changes are related to each other then it most likely needs to be more than one PR
• Any Public API changes are explained in the PR details and conform to existing APIs

Testing

• I have included test coverage for these changes, or explained why they are not needed
• All automated tests pass, or I explained why that is not possible
• I have personally tested this on my device, or explained why that is not possible

Final pass

• Code is as readable as possible.
  • Simplify with less code, followed by splitting up code into well named functions and variables, followed by adding comments to the code.
• I have reviewed this PR myself, ensuring it meets each checklist item
  • WIP (Work In Progress) is ok, but explain what is still in progress and what you would like feedback on. Start the PR title with "WIP" to indicate this.

@shepherd-l Is there any reason that we update IOS to 5.1.0 instead of 5.1.1?

[shepherd-l]

@jinliu9508 I think 5.1.0 is the latest release of iOS. Could you show me where you found a 5.1.1 release?

This sounds ok to me, since you must target Android 33 to release to the Play Store now, anyway.

@jinliu9508 I think 5.1.0 is the latest release of iOS. Could you show me where you found a 5.1.1 release?

Yes you are correct, 5.1.1 IOS is only in draft mode. This looks good to me know.
